I get
warning: collision encountered: ...
warning: arbitrarily choosing /gnu/store/89
messages,
What do they mean? and How to fix?

more detail. I install a package, here I use autojump as arbitrary example:

Does this explanation make sense?
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=22402#37

If so, then you should read the warnings and investigate which files are
colliding. Some, like the hicolor icon-theme.cache, seem harmless to me,
although I welcome a second opinion.

I don't know about this one. Files the .la extension are used by libtool
but I don't have enough experience with libtool or know enough about
libatomic to know if this is going to be a problem.

Yes this is a continuation of my previous question. Thanks for response. I
didn't
show the complete output. But I tried to show there are 13987 LINES in the
error
messages. It's not so much the particular cases, it's Why is this happening
at all?
Did I do smething wrong or is this software error? ANd, what is the proper
procedure to
removal of one of the options?
Is it something like:   <http://libatomic.la>
guix package -r /gnu/store/wfvxxpdhnzd59vkad1zasm4f858giv9a-gcj-4.9.3/lib/
libatomic.la
or is it
guix package -r /gnu/store/wfvxxpdhnzd59vkad1zasm4f858giv9a-gcj-4.9.3
or is it
guix package -r / gcj
And can it be done globally?
THere must be something I'm not doing correctly.

Shirlie, that can't be right?
BTW
ls -1 /gnu/store|wc
 14580   14580  849158
does that seem reasonable?

You would not actually install all these differing builds of the same
version of acl into your profile.

Yes, the store contains a large number of files.

The cause is that you installed some packages that happen to contain
the same paths.

In your current Guix profile, there are multiple packages providing
those "colliding" files.

You could try splitting your profile up into different package manifests
[0] that are organized around specific tasks you need to do. Then, you
can create a new profile based on that manifest when you want to use
those packages. Based on the collision between gcj and gccgo, you could
create one manifest for Java programming, one for Go programming, etc.
This would reduce the chance of collisions by reducing the set of
packages in your profile at any given time, but that's it. And of
course, you may actually need to use gcj and gccgo together, in which
case this approach would not be an option.

Also, once in a while I need to use a program for a little while and I
don't expect to need it again for a long time and I don't care if it
gets garbage collected later on. In that case, I (ab)use `guix
environment --ad-hoc` to just get it momentarily in that shell.

I welcome other users' suggestions on mitigating collisions!

My understanding is that collisions are addressed on a case-by-case
basis, sometimes at the package level, or sometimes in the build system
as discussed in this thread:

$ guix package -r gcj

You cannot remove "components" of the gcj package as attempted in some
of those examples.

If you are using Guix on a "foreign distro", then there is no concept of
global packages — you only are affected by your current profile. On
GuixSD the administrator may provide global packages in the system
declaration.

Nope! ;)

> 2354 packages in profile

What command did you use to install 2354 packages into your personal
profile?  Why would you install 2354 packages in your profile?

There are packages that provide files of the same name; for example
“samtools-0.1” and “samtools” both provide “$out/bin/samtools”.  When
they are both installed in the same profile, there is an obvious
collision.  People don’t install both these packages into the same
profile, because there is no way to disambiguate the colliding files.
Instead they will install them into *different* profiles using something
like

    guix package -p /path/to/profile -i samtools

If you feel the need to install all available packages into your profile
you’re doing it wrong.  Each package has its own directory in
“/gnu/store”, but profiles are the union of the files of each of the
directories of selected packages; at this point collisions may arise.

To resolve serious collisions remove one or the other package from your
profile.  Install it in a separate profile instead.
